SPECIFICATION forming part of Letters Patent No.361,186, dated April 12,1887.

I Application filed July 23, 1886. Serial No. 208,843. (No model.)

TO'aZZ whom it may concern:

Be it known that I, WILLIAM W. BIrcHEY, a citizen of the United States,residing at Archie, in the county of Cass and State of Missouri, haveinvented certain new and useful Improvements in Ohurns; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates toimprovements in churns or ice cream freezerswith provision for driving a buffingwheel or other device, whichimprovements will be fully understood from the following description,taken in connection with the annexed drawings.

Figure 1 is an elevation of the improved device, a portion of the vesselof which is broken away to show parts of the contained dashers. Fig. 2is a vertical diametrical section through the device.

Referring to the annexed drawings by letters, A designates a vessel ofsuitable capacity, preferably cylindrical, and provided with a removablecover, A through which is a central aperture. V

G designates a dasher of an open or skeleton form having vertical barsformed entire with horizontal bars. This dasher is suitably secured toadash-rod, O'fiwhichis connected to the lower stem of a beveled pinion,E, by a socketpiece, 0, and a set-screw, 0 This upperstem of thispinionE passes through an arm, I), of a standard, B, rigidly secured tothe cover A and receives a nut, 0 on it, and, if desired, a washer, C.Pinion E engages with a large bevel gear-wheel, D, the shaft d of whichis journaled in the said standard B and bears a winch, H- This wheel Dengages with a pinion, F, on the upper end of a tube, Z, which isjournaled in the arm b of said standard B, and revolving freely throughit is the dasherrod 0.

G designates the outer dasher, of a similar shape to the inner dasher,G, and it is removably secured on the screw-threaded end of the tube Zby means of a nut, 19. By these means the outer dasher, G, can bevertically adjusted on the tube Z to properlyadapt it to the dasher G,or the dasher G can be removed from its sleeve, when necessary, bysimply removing the said nut 19, the dashers first being removed fromthe vessel A. The waved portions of the outer dasher, G, are oblique tothe dasher-rod 0 as shown in the drawings, and have suitably secured tothem straight stirring and clearing blades 9 which are inclined in thesame direction with respect to the inner sides of the vessel A, as shownin the annexed drawings, Fig. 2. It will then be seen that while theupper end of one blade is clearing the cream from the side of the vesselA the lower partof the opposite blade is clearing the cream from theopposite side of this vessel, and vice versa. The blades thus diagonallyor obliquely arranged not only servev as clearers, but they also serveas stirrers to prevent the cream becoming lumpy while being frozen.

It will be observed that when the gear-wheel D is rotated the dashersreceive rotation in opposite directions; also, that the dashers arereadily removable from the rod and sleeve.

lV designates a standard rigidly secured to the sides of the vessel A,round in cross-section, and M designates a bracket bearing, which can beturned about the standard W when the set screws m are loosened. Thisstandard affords a j ournal-bearing for the short shaft of a bevelspur-wheel, X, adapted to engage with the gear-wheel D when in theposition shown in Fig. 1. The spur-wheel X engages with a pinion, X on ahorizontal shaft,

X, also journaled in the standard M.

I have represented a buffer or grinding wheel, P, on the outer side ofthe shaft X, which may be rapidly rotated by turning the winch H; but Icontemplate the device for transmitting motion to a coffee-mill,salt-pulverizer, and other light driving devices. By loosening theset-screws m m the bracket M can be swung around, relieving the wheel Xfrom the wheel D.
